Abstract

PURPOSE: To manufacture the rod of irregular section in which the thin walled middle portion is provided with good surface condition, by previously forming a longitudinal continuous groove in the middle portion of the metallic rod blank, and by placing the triangular type tip portion of the pressure plate in this continuous groove so as to press the middle portion of the metallic rod blank.
CONSTITUTION: In the middle portion of the metallic rod bland 10, the small groove 11 is continuously formed along the longitudinal direction. While this metallic rod blank 10 is being intermittently moved in the longitudinal direction, the middle portion of the metallic rod blank 10 is successively pressed by the pressure plate 3 providecd with tip portion 4 of approximately triangular shape, so as to fit the tip portion 4 into the R-type small groove 11, and to reduce the thickness of the middle portion; hereby, the rod 2 of irregular section in which the thickness at both ends is thinner than thickness of the middle portion. According to this method, the product of irregular section provided with smooth surface freely from indentation, etc., is manufactured.
